8 Common Signs And Symptoms Of A Vitamin D Deficiency

Vitamin D, known as the "sunshine" vitamin, plays an extremely important role throughout your body. Functioning like a hormone, vitamin D helps to boost the absorption of calcium and phosphorus that work together to make your bones stronger.

However, as one of the easiest deficiencies to develop, vitamin D deficiency is common and it is estimated that about 1 billion people worldwide aren't getting enough vitamin D. According to a study, 41.6% of adults in the US have low levels of vitamin D in their bloodstream.

Without enough vitamin D, your overall health can suffer. Your bones can become brittle, which can cause easy breaks and fractures and lead to a higher risk of developing osteoporosis. You could also become more prone to certain types of cancer and psychological issues like depression and anxiety.

How much vitamin D do you need? Generally, the recommended amount is 800-1,000 units a day, but that amount varies according to your age.

Who are more susceptible to vitamin D deficiencies? Those who always stay indoors or use sunscreen when going out, those who are elderly, overweight or obese, those who eat less fatty fish or fortified dairy products, and those who live areas where there is little sun year round.

How to tell if you have developed a vitamin D deficiency? The best way is to have a blood test. Certain signs and symptoms, however, could also indicate that you aren’t getting enough vitamin D. Just check out these 8 common symptoms of vitamin D deficiency.

Remember, do check with your doctor before making any serious lifestyle changes.

Low Vitamin D Symptom #1: Frequent Sickness

One of vitamin D's key functions is keeping your immune system strong, so you are better able to ward off viruses and bacteria that can cause infections and illness. Vitamin D directly interacts with the T-cells of the immune system that are responsible for fighting off various "invaders" that cause disease.

Vitamin D deficiency can weaken your immune system and, as a result, you'll become more susceptible to sickness. Several studies have shown that low levels of vitamin D contribute to the development of respiratory tract infections such as colds, bronchitis, and pneumonia. Not getting enough vitamin D, you also run a higher risk of developing chronic disorders like COPD.
